- Application filed To all whom iii-may comer-1i;

Be it known that I, GEORGE L. RmeHnnnM,

a citizen of the United States, and a resident of Jersey City, in thecounty of Hudsonand State of New Jersey, have invented certain newuand useful Improvements in Pliers, of

' saidbracliet-at itsr'lower en is sup orted on whichthe following isaspecification...

I This invention relates to" twistingand bending l1ers. Its-- object is the produc tion .of p iers, by means .of which wire canbe cut in suitable lengths and with'consecutive, movementsof the eratingelementsof the invention, bendsai lengths into loops and fasten them about a" pair of-main' or bodywires to join- .the latter while the operator presses on an operating-lever of the -pliers. v g I The organization'of the inventioncomprises essentially reciprocating and rotating guide jaws fora loop 'wire, which is caused to be clamped to apalr of body wireslocated between the said jaws. v

Figure 1 represents a'front view of a pair shows a left hand side view-of Fig shows an enlargedfra-gmentary view of Fig.

At thelower endsof the guidev rods are rooves 41. At the lower end of the guides aft. 36 'is' formed the rectangular ad usting lug l Ifatented'M'ar. 8,. 1910.

and from the latter extends the pinion 46.

The lug 45 and pinion 46- are located in-the opening 33 of the bracket 32;

'. .-A pin 47 with the enlarged portion 48 and-- the collar- 49 is journaledin. the frame 20 and the bracket 32. On' the larger portion of the said pin 47 is journaled' a disk 50 having the toothed segm tendin from its circumferential edgeIand paralle out with the teeth 51 eat-- with the planerofits surface, the

toothed segment adjacent thereto" with its teeth 53 'perpendicu ar to the lane of its surface, and the cam 54 exten ing around the circumference thereof between the ends of the said segments The teeth 51 have the V grooves 55 extending inwardly from their outer ends.

A roller 60is journaled on the pin 61 extending from-said disk 50. 1A pinionf62 is located on the-outer lower side ofthe frame 20' andisfastenedto the larger portion of the pin-47.. A pinion 64 is journaledon a pin 65 extending from the frame 20.,- and itsteeth 66 mesh with the teeth 51. The said teeth have. V grooves67 similar tothe. grooves- 55; A. wire guide 'bracket'70= with: the guide-channelfll is.-

A guide screw [D1181 extends from said shank 79 and engages with anopening 82 in the frame 20.

In the lower portion of thecam frame 75 is formed the cam 83 that engages with the roller 60. With the said cam frame 75 are also formed the legs 84 which are connected by the tie brace 85, that engages the grooves 41 in the cross-heads 40, and an opening 86 in the frame 20 provides clearance for the.

cross-heads 40.

On the frame 20 is adjustably fastened the cutting blade 90 by means of screws 91 that engage the elongated opening. '92 in the frame 20, and are in threaded engagement with openings blade 90. A threaded bracket 95 extends up from the frame 20 and supports the ad usting screw 96 that can bear against the shank of the blade 90. I

A guide conduit 100 having the funnel shaped opening 101 for the loop wine is fastened to the frame 20. Its lower opening 4 101 is located above the pinion 64 and segthe legs 84 of the -upper end takes a which at its other-end iswound aroun ment with the teeth 51, and is in line with the channel 71 of the guide bracket 70. The conduit 100 extends across the frame below guide frame 75, and 1ts irection axial with the openings through the ide jaws 39. From the rear side 0 the frame 20 extends the screw pin 105 on which is hinged the operatin arm 106 having formed at 1ts lower en the toothed segment 107, the teeth 108 of which -mesh with the teeth of the pinion 62. A stop 102 for these cut 107 extends from the frame 20. Wit ,the arm 106 is formed the handle 109, and on the inner side of the latter bears a sprin 113 an fastened to a block 111 extending from the frame 20. I f I The invention could be modified in various ways, and rings could be formed with the upper ends of theguide rods 38 in place of the guide jaws 39.

- when starting operations,

The pliers are shown in their normal position particularly in Figs. 1, 2 and 7, and the arm 106 is swung to approach the lower portion of the frame 20, when the teeth of the segment 107 meshing with the teeth of the pinion 62 causes the latter to be partially turned. The pin 47 turns with the pinion 62, and the ratchet wheel' 56 turns .with said pin, and after a slight rotation engages the pawl 57, which causes the disk 50 and consequently the pinion 66 meshing with the segmenthav ing the teeth 51 to partially turn. The loop wire 25 being in engagement with the thence throng in the shank of-said cutting -36 with its "pinion 62, -the pin v bonus grooves of the teeth of the pinion 66 and with the grooves of the teeth 51, is forced through t e uide conduit 100 and from the openings in the guide jaws 39 as shown particularly in Fig. 8. The operator continuing to force the arm 106 a little closerto the frame 20, and the roller engaging down carrying with it the cutting blade 80 which severs the loop wire to a proper length for one of the loops to be formed as shown enlarged in Fig. 12.

to be pulled down, wire is formed into the body wires 115, 116 or other objects as by virtue of which the shown in Figs. :9 and 13. While the cam.

frame is being pulled down, the cam 54 with the cam 83 of the cam frame 75, the latter is pulled While the wire is beingout theengagement of the tie brace 85, with the cross-heads 4O causesthe guide rods 38 the U shaped loop over of the disk 50 is engaged with one of the faces of the rectangular adjusting lug 45 and the guide shaft 36 is consequently prevented turning, and locked fromrotation. 'Upon a furtherapproach of the arm 106 to the frame 20, the teeth 53 'enga teeth of the pinion 46 causes t e guide shaft ide rods .38 to be turned one and one-hal turning of the shaft 36 the engagement of the loo wire 25 with the 'aws 39 causes the ends'o the said loop-to e wound around the body wires 115, 116 and to have its ends finally pushed up to hug the body of the loop. The forms of the loop for the first, second, third and fourth quarter of the first revolution, and the first quarter of the second revolution ofthe shaft 36 areshown reshown the finished loop formed during the second quarter of the second revolution, with the ends of theloop wire hugging the body thereof. Upon the further movement of the arm 106 the teeth 53 are again disengaged from the pinion 46, and the adjusting lug 45 is' againin engagement with the cam 54 to prevent the shaft 36 turning, roller 60 coacting with the cam 83, the cam frame 75 with the cutting blade 80, and the guide rods 38 are pushed up to their normal ositions' for a second'operation. Upon reeasing the operating-arm 106, the spring 110'bearing on the inner face of the handle 109 and the segment 107 coacting with the 47 is turned a revolution in a direction pposite that.- of the arrow in Fig. 5 and the pawl 57 sliding on the edge of the ratchet wheel 56, the latter is located in its original position.
